The profit on a certain television set is 16.5% of the cost price. If the profit is $330,
Find:
a) the cost price
b)the selling price of the television

Hi Alex,

Selling price = cost + profit

so

Selling price = cost + $330

You are told that $330 is 16.5% of the cost so

$330 = 0.165 × cost.

Solve this equation for the cost.

I hope this helps,
Penny
